Subglacial Lake Vostok lies 4000 meters below Vostok Station, in East Antarctica. water from the surface, but also from the water deeper inside the Russian scientists have made a new borehole into Lake Vostok, the prehistoric Antarctic water mass, which has been sealed for millions of years – three years after a previous mission was prematurely ended by an accident resulting in sample contamination. A cross-section of Lake Vostok shows how ice accumulates above the lake, and a list of some of the different organisms discovered in the ice core. "The types of organisms we found suggested they derived their energy from minerals present in the lake and sources from the underlying bedrock," Christner said. have a clearer idea of where the water surface is located. Because of this, Rogers believes there are most likely a multitude of others from the lake, opening the door to further research. “We will need many years to fully interpret what we find, and © water surface at the depth of 3,769 meters and 15 cm. "[Yet] I believe most of its secrets remain.". Using a RADARSAT dataset of Antarctica, an abandoned Russian station on top of frozen Lake Vostok is visible. "Lake Vostok is one of the easiest subglacial lakes to detect due to its size," Christner said. Researchers have mapped Lake Vostok's shape with remote sensing techniques, such as seismic soundings and ice-penetrating radar. The researchers took samples from two areas of the lake: the southern main basin and near an embayment on the southwestern end of the lake. making the world media swoon. ago. Will our solar system survive the death of our sun? into the water mass,” says Lukin. Why has our normal body temperature been dropping? Read RT Privacy policy to find out more. This website uses cookies. This constant replenishment from melting ice means the water in the lake may be relatively young, just thousands of years old, according to ice core studies. By sequencing the DNA and RNA taken from samples of accretion ice (frozen lake water attached to the bottom of the overriding glacier), the team discovered far more complexity than anyone thought, said Rogers, according to a press release. life forms in space, because we believe the most promising life ensures that the collected water – up to 1 liter in volume – is The presence of a large buried lake was first suggested in the 1960s by a Russian geographer/pilot who noticed the large, smooth patch of ice above the lake from the air. There was a problem. But the scientific results produced Scientists are hoping to find life forms in the pristine cold resources minister Sergey Donskoy, as the expedition hit the They chose to include only those sequences which they were absolutely certain came from the accretion ice.

"The lake has been ice-covered for at least 15 million years," said Brent Christner, a Louisiana State University biologist who has examined ice cores collected above the lake. Russian drilling team during the Antarctic summer three years In addition to fungi and two species of archaea (single-celled organisms that tend to live in extreme environments), the researchers identified thousands of bacteria, including some that are commonly found in the digestive systems of fish, crustaceans and annelid worms, according to the press release. pressure made it shoot up hundreds of meters, mixing it up with Subscribe to RT newsletter to get stories the mainstream media won’t tell you, A satellite view of Antarctica (Reuters/NASA). This particular lake’s existence, in the vicinity of Vostok Station in East Antarctica, was first postulated in the 1960s by Andrei Kapitsa, a geographer and Antarctic explorer. Follow LiveScience @livescience, Facebook & Google+. The lake itself is 143 miles (230 km) long, 31 miles (50 km) wide and as much as 2,625 feet (800 meters) deep. the Freon and kerosene used to keep the borehole from freezing. "Many of the species we sequenced are what we would expect to find in a lake," said Rogers. Receive news and offers from our other brands? These "extremophiles" could mimic life on other moons and planets, such as Jupiter's icy moon Europa. Its only water supply is meltwater from overlying ice sheet, Christner said. St.Petersburg Vestnik newspaper ahead of the borehole completion. The surface of the lake – now listed as the sixth biggest in the scientific value,” said Russia’s environment and mineral After two years of computer analysis, the final results reveal that Vostok Lake contains a diverse set of microbes, as well as some multicellular organisms.

New York, the past,” said Lukin, who noted that this time scientists Lake Vostok is located at the southern Pole of Cold, beneath Russias Vostok Station under the surface of the central East Antarctic Ice Sheet, which is at 3.488 m above mean sea level. In the 1990s, Christner was part of an international team that discovered microbes in frozen lake water collected above Lake Vostok's liquid surface, called accretion ice. Worse than that, in an unintended imitation of modern drilling SCAR workshop on Lake Vostok Sub-Glacial Lake Vostok: Science Opportunities and Technological Challenges.

Lake Vostok is one of the largest lakes on Earth in size and volume, rivaling Lake Ontario in North America. Live Science is part of Future US Inc, an international media group and leading digital publisher. The previous drill-through to the surface of the water, which is When the drill bit reached the water in February 2012, the Scientists are hoping to find life forms in the pristine cold water – twice as pure as double distilled mineral water – that have no equivalent on Earth, but may exist somewhere else in the universe. water – twice as pure as double distilled mineral water – that An artist's cross-section of Lake Vostok, the largest known subglacial lake in Antarctica. from that mission were negligible, due to an accident that set © Autonomous Nonprofit Organization “TV-Novosti”, 2005–2020. To this end, a special 50 kg probe has been developed, which the ice, while the rest of the borehole below them quickly froze. But the true age of the lake water is unknown. Read RT Privacy policy to find out more. “But we are also more ambitious – we do not only plan to take thousands of life forms, no one could guarantee that it was free Although samples taken from the water in the lake showed not adulterated by the antifreezing agents. Antarctic Lake Vostok 'might have fish' Published. “This is an event of worldwide significance, which has huge the team’s work back by years. Listen to “Episode 101: Lake Vostok Monster and Dyatlov Pass Incident” on Spreaker. NY 10036. Liquid water is thought to take thousands of years to pass through the lake, which is the size of North America's Lake Ontario. of contamination. significant discovery, showing that conditions that are totally Rogers emphasizes that the team erred strongly on the conservative side while reporting their findings. The long, narrow lake may lie in a rift valley, similar to Lake Baikal in Russia. "Most of the organisms appear to be aquatic (freshwater), and many are species that usually live in ocean or lake sediments.". methods, the pressure produced a hydraulic fracture about 3,300 And how soon will the world know if there really are alien life sunlight for over 15 million years, before it was reached by a forms exist where there is water, including the Jupiter satellite Covered with ice for millennia, cut off from light and contact with the atmosphere, Lake Vostok is one of the most extreme environments on Earth.

[Image Gallery: Alien Life of the Antarctic]. Workshop in Cambridge (UK), September 26-27, 1999. sponsored by the Scientific Committee on Antarctic Research (SCAR). Rogers notes that the presence of both marine and freshwater species supports the theory that the lake once was connected to the ocean, and that the freshwater was supplied by the overriding glacier. Analysis of the life forms suggests Lake Vostok may harbor a unique ecosystem based on chemicals in rocks instead of sunlight, living in isolation for hundreds of thousands of years. was hailed as one of the biggest geological discoveries on Earth, have no equivalent on Earth, but may exist somewhere else in the re-drilling those last 500 meters, through a parallel borehole. – In this episode, we travel to the frigid, near inhospitable locations of Antartica near the South Pole and Siberia, Russia – Oscar Spectir walks us through the mystery of Lake Vostok and the terrifying Antarctic cryptid known only as “Organism 46-B” Shares.
